Seats and Seat Controls
This section tells you about the seats -- how to adjust
them, and fold them up and down. It also tells you about
reclining front seatbacks and head restraints.
Manual Front Seat
CAUTION:
You can lose control of the vehicle if you try to
adjust a manual driver's seat while the vehicle is
moving. The sudden movement could startle and
confuse you, or make you push a pedal when you
don't want to. Adjust the driver's seat only when
the vehicle is not moving.
If your vehicle has a manual bucket or split bench seat,
you can adjust it with this lever located at the front of
the seat.
Lift the lever at the front of the seat to unlock it. Using
your body, slide the seat to where you want it. Then,
release the lever and try to move the seat with your body
in order to make sure the seat is locked into place.

adjustment, you can
increase or decrease
lumbar support in an area
of the lower seatback.

reaches the desired level of support.
To decrease support, press and hold the rear of the
control. Let go of the control when the lower seatback
reaches the desired level of support.
You can also reshape the side wing area of the lower
seatback for more lateral support.
To increase support, press and hold the top of the
control. Let go of the control when the lower seatback
reaches the desired level of support.
To decrease support, press and hold the bottom of the
control. Let go of the control when the lower seatback
reaches the desired level of support.

controls the driver's
seat cushion and recliner
positions and is located
on the driver's door
trim panel.

Liftgate Caution
CAUTION:
It can be dangerous to drive with the liftgate
glass, liftgate or rear doors open because carbon
monoxide (CO) gas can come into your vehicle.
You can't see or smell CO. It can cause
unconsciousness and even death.
If you must drive with the liftgate glass, liftgate
or rear doors open or if electrical wiring or other
cable connections must pass through the seal
between the body and the liftgate glass, liftgate
or rear doors:

Make sure all other windows are shut.

Turn the fan on your heating or cooling
system to its highest speed with the setting
on MAX A/C. That will force outside air
into your vehicle. See ªComfort Controlsº
in the Index.

If you have air outlets on or under the
instrument panel, open them all the way.
See ªEngine Exhaustº in the Index.
Liftgate Glass and Liftgate
To open a mechanical lock system from the outside,
insert the key into the lock and turn it counterclockwise
to unlock the glass and liftgate.
The liftgate glass can be opened using the pushbutton on
the liftgate after the doors have been unlocked. This can
be done by using either the power door locks or the
remote keyless entry system.
To open the entire liftgate, lift the handle located in the
center of the door.
To lock a power lock system from the outside, insert the
key into the lock button and turn clockwise. All doors will
lock. You may also use the keyless entry system or the
power door locks to lock the liftgate and liftgate glass.
Panel Doors
To open the rear panel doors, you must open the
passenger's side panel door first. If the door is locked,
insert your door key in the lock and turn it
counterclockwise to unlock it.
To open the passenger's side panel door, pull on the
handle and pull the door open.

3-10 Rear Air Conditioning and Heating Systems
with Electronic Climate Control System
(If Equipped)
Front Control
Rear ControlWith this system the rear passengers can control the
temperature of the air flow for his/her own zones.
The climate control has three controls.
To adjust the airflow speed, turn the fan control knob
located on the left side of the control panel to the desired
blower setting.
The system also has a front AUTO setting that can
automatically change the temperature of the rear seating
area based on information from the front control. An
OFF setting, located on the front climate control panel,
also allows the driver to turn off the rear passenger seat
controls from the front seat.
To adjust the air temperature, turn the temperature knob
on the center of the control panel.
For warmer air, turn the knob clockwise toward the red.
Turn the knob counterclockwise toward the blue for
cooler air.
To regulate the airflow location, adjust the right knob on
the control panel. Turn the knob clockwise for floor vent
airflow or counterclockwise for headliner vent airflow.
Generally, the upper vents are used for air conditioning
and the floor vents for heating. The control knob can be
set to any blend setting.
For rear control operation, use the above instructions.

3-28 Rear Seat Audio (If Equipped)
This feature allows rear seat passengers to listen to any
of the music sources including AM
-FM, automatic tone
control, cassette tapes and CDs. However, the rear seat
passengers can only control the music sources that the
front seat passengers are not listening to. For example,
rear seat passengers may listen to a cassette tape through
headphones while the driver listens to the radio through
the front speakers. The rear seat passengers have control
of the volume for each set of headphones. Be aware that
the front seat audio controls always override the rear
seat audio controls.
Note that this feature is intended for rear seat passengers.PWR: Press this button to turn the rear seat audio
system on or off. The rear speakers will be muted
when the power is turned on. You may operate the
rear seat audio functions even when the primary radio
power is off.
VOL: Press this knob lightly so it extends. Turn the
knob clockwise to increase volume and counterclockwise
to decrease volume. Push the knob back into its stored
position when you're not using it. The upper VOL knob
controls the upper headphone and the lower VOL knob
controls the lower headphone.
AM
-FM: Press this button to switch between AM, FM1
and FM2. If the front passengers are already listening to
AM
-FM, the rear seat audio controller will not switch
between the bands and cannot change the frequency.
SEEK: While listening to AM
-FM, press the up arrow
to tune to the next higher station and stay there. Press
the down arrow to tune to the next lower station and stay
there. The sound will mute while seeking. The SEEK
button is inactive if the AM
-FM mode on the front
radio is in use.
While listening to a cassette tape, press the up arrow to
hear the next selection on the tape. Press the down arrow
to go back to the previous selection. The SEEK button is
inactive if the tape mode on the front radio is in use.

Here's how anti-lock works. Let's say the road is wet.
You're driving safely. Suddenly an animal jumps out in
front of you.
You slam on the brakes. Here's what happens with ABS.
A computer senses that wheels are slowing down. If one
of the wheels is about to stop rolling, the computer will
separately work the brakes at each front wheel and at
both rear wheels.The anti
-lock system can change the brake pressure faster
than any driver could. The computer is programmed to
make the most of available tire and road conditions.
You can steer around the obstacle while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.
